Algebraic fiberings of groups

October 31, 2025 - 3:00 pm to 4:00 pm

ESB 2012 and Zoom

We say that a finitely generated group algebraically fibers if it admits a homomorphism onto the integers with finitely generated kernel. This is a group theoretic analogue of the manifold property of being a fibre bundle over a circle. In this talk, I will give an overview of ... Read more

Expansion coefficients of powers of Vandermonde determinants

November 4, 2025 - 3:30 pm to 4:30 pm

ESB 4127 (PIMS)

Powers of Vandermonde determinants serve as model wave functions for the fractional quantum Hall effect. In this talk I will explain how one can realize the coefficients in the monomial basis as expectation values of operator products and how this captures the relevant ... Read more

On the energy image density conjecture of Bouleau and Hirsch

November 5, 2025 - 3:30 pm to 4:30 pm

We affirmatively resolve the energy image density conjecture of Bouleau and Hirsch (1986). This conjecture generalizes a foundational result in Malliavin calculus: the non-degeneracy of the Malliavin matrix of a random variable implies absolute continuity of its law. This ... Read more

Patching and the nine-term Mayer-Vietoris sequence for complexes of tori

November 24, 2025 - 3:00 pm to 4:00 pm

MATH 126

We present the patching method, a machinery developed by Harbater–Hartmann–Krashen and various other authors, dedicated to the study of arithmetics of linear algebraic groups over function fields of curves over complete discretely valued field such as ℚₚ(T). Then, we present a ... Read more

Subcritical two-point functions for high-dimensional statistical mechanical models

November 26, 2025 - 3:30 pm to 4:30 pm

ESB 2012

The subcritical two-point function for the Ising model, percolation, or the self-avoiding walk on Zd, decays like its critical counterpart when x is small, and exhibits the Ornstein--Zernike decay when x is large. We report recent progress on the slightly subcritical two-point ... Read more
